Its range is upto 50 Km. WiMAX is currently expected to replace existing DSL and other cable broadband technologies like various companies are employing WIMAX to provide broadband connections. WiMAX will also be as painless as WiFi -- turning your computer on will automatically connect you to the closest available WiMAX antenna. Wi-Fi (802.11) has couple of varieties and some of them are 802.11a, 802.11b, 802.11g and 802.11n. Here in this article, Let us discuss about few points which makes WiMAX different to Wi-Fi. It currently provides 40 Megabits per second for one wireless channel for both fixed and mobile applications.WiMAX can deliver uplink speed of 25 Megabits per second (Mbps) and downlink speed of 63 Megabits per second (Mpbs). It may interfere with each other and with cordless phones also. (4) Wi-Fi uses CSMA/CA protocol which could be connection based or connection less whereas WiMAX uses connection oriented MAC protocol. Experience. This technology is based on IEEE 802.16. For line of sight connectivity, with the help of strong antennas, coverage area of up to 9300 square kilometers (sq-kms) is possible. Wi-Fi can transmit data at the fastest, up to 54 Megabits per second, whereas speed for WiMAX can reach up to 70 Megabits per second. WiMAX and Wi-Fi are both wireless technologies but Wi-Fi can only be operated in short ranges (Max 250 m) and WiMAX could be operated in long ranges (around 30 Km). Wi-Fi products are used to build WLANs, while WiMAX products are used to build WMANs.

WiMAX can be used for long ranges. Required fields are marked *, All about Electrical & Electronics Engineering & Technology. (2) Wi-Fi a short range technology mostly used in, in-house applications whereas WiMAX is a long range technology to deliver wireless broadband to far end. This feature allows service providers to manage the network traffic based on the subscriber agreement and charge the subscriber extra for Quality of Service (QoS) protection. It is used to provide higher data rates with increased coverage. One popular use of the Wi-Fi standard is in hotspots that offer mobile user’s the ability to connect to the Internet with their Wi-Fi enabled wireless computers and devices. There is no need to resubmit your comment. All rights reserved. Wi-Fi does not guarantee any QoS but WiMax will provide your several level of QoS. Wi-Fi operates in spectrum which is unlicensed. However, both are IEEE standards. "Difference Between WiMAX and Wi-Fi." Flexible channel sizes from 1.5MHz to 20MHz. Popular versions are 802.16a, 802.16d and 802.16e. 802.11a,b,g operates in 2.4 GHz frequency and range from 40-140 meters (in reality) and 802.11n operates in 5 GHz with OFDM modulation technology thus results higher speed (40Mbps in reality) ranged to 70-250 meters. Wi-Fi uses techniques similar to the Ethernet standard to specify how physically to configure a wireless network. By ensuring Quality of Service and Multicasting services, WiMAX can provide Voice over Internet Protocol (VoIP) and Internet Protocol Television (IPTV) apart from fast broadband connections. In this article, we'll find out how WiMAX works, what engineers are doing to make it better and what it could mean for the future of wireless Internet. A computer or a laptop, which is equipped with WiMAX, would receive data from the transmitting station, using encrypted data keys. Wi-Fi is intended for LAN applications, users scale from one to tens with one subscriber for each CPE device. WiMAX technology provides two types of wireless services – Line of sight service with operating frequency band up to 66 GHz, whereas for non-line of sight service, the operating frequency is between 2 to 11 GHz. Unlike WiMAX, Wi-Fi provides only line of sight connectivity. WiMAX and Wi-Fi are both wireless technologies but Wi-Fi can only be operated in short ranges (Max 250 m) and WiMAX could be operated in long ranges (around 30 Km).

While WiMAX is the latest step in the area network scale, the final step would be the Global Area Network (GAN) (Proposed Standard – IEEE 802.20). As such, WiMAX can bring the underlying Internet connection needed to service local Wi-Fi networks. WiMax stands for Wireless Inter-operability for Microwave Access. While Wifi is based on IEEE 802.11 standard, WiMAX is based on IEEE 802.16 standard. It does not require line of sight and can efficiently bandwidth intensive applications like real time video.
